First graders were chemists in lab. Making slime is such a fun way to show how states of matter can change! We mixed two liquids (PVA and a cross-linker solution) and created a solid. The molecules link together and create a polymer (a long chain of molecules).
Last May, we hatched three ducklings in the Science Lab (Uno, Zip, and Percy). They live on the retention pond behind the school. They have imprinted on me, so watch what happens when I call them to eat. Click below.
I asked the children why they think we put water on plants to make them grow? Could another liquid help a seed grow better than water? We took this question through the steps of the Scientific Method and completed a lab report. We tried to keep all the variables (other than the liquid) the same. We used the same seeds, pots, and soil. They received the same amount of sunlight and we poured 50ml of the liquid on each seed at the same time. I had helpers from each class help me apply the liquids (water, Sprite, apple juice, vinegar, and milk) every other day. We continued this experiment for two weeks. We had to stop because our milk container suddenly had maggots and the apple juice drew fruit flies. We also noticed the vinegar smelled. Only the seed that we watered grew at all. We learned a lot!
Farmer Sue taught us some interesting facts about donkeys. Look at the donkeys below. What do you notice on the back of each of them? Legend has it that because the donkey carried Jesus into Jerusalem, God marked donkeys with a cross. Each donkey has a unique cross which is how farmers tell them apart.
